Anguillid herpesvirus 1 (AngHV) is an important viral pathogen affecting eel. This study was designed to investigate the potential molecular mechanisms and immune response elicited at the protein levels in the skin mucus of AngHV-infected Anguilla anguilla. Tandem mass tag (TMT)-labelling proteomics with the liquid chromatography tandem mass spectrometry (LC-MS/MS) was used for performing quantitative identification of the proteins. In addition, the quantitative protein amount was detected by parallel reaction monitoring (PRM) analysis. A total of 3486 proteins were identified, of which 2935 were quantified. When a protein fold change was greater than 1.3 or less than 0.76, it indicated a differentially expressed protein (DEP). Overall, 187 up-regulated proteins and 126 down-regulated proteins were detected, and most of the DEPs were enriched in the CAMs pathway, intestinal immune pathway, herpes simplex virus 1 infection pathway, phagosome pathway and p53 signaling pathway. The results of the DEPs detected by PRM were highly consistent with the results of the TMT-labelled quantitative proteomic analysis. The findings of this study provide an important research basis for further understanding the pathogenesis of AngHV.
